LAMP-BURNER.

Specification of Letters Patent.

Patented May 21, 1918.

To all whom it may concern:

Be it known that we, FLOYD O. Hmns and \VLLLix c'rox MILLs, citizens ofthe United States, residing at Milan, in the county of Erie and State ofOhio, have invented cer tain new and useful Improvements in Lamp-Burners, of which the following is a specification.

This invention relates to lampburners of the central draft tube type,and has forits object to provide improved means for supplying air forcombustion or vaporization of the kerosene or other fluid fuels.

A further object of the invention is to provide improved means forsupporting and adjusting the wick, and holding the mantle and chimney inposition.

'A further ob ect of the invention is to generally improve the structureof such burners as will more fully appear from the following descriptionand accompanying drawings.

In the drawings Figure l is a central vertical section of the burner.

Fig. 2 is a similar section at a right angle to Fig. 1.

Figs. 3, 4 and 5 are sections on the line 33, 44, and 55, respectively,of Fig. 1.

Figs. 6 and 7 are details of fastening devices to hold the parts of theburner together.

Referring specifically to the drawings, 1 indicates an inverted conicalor flared base which screws as at 2 into the neck of the font 3. At theupper end of this base is a cylindrical part 3. Within this cylinder isa circular shell 4 the lower part 5 of which is conical, and has at itslower edge a horizontal rim 6 with an upstanding flange 7 at the edgethereof. This shell or member 4 is inserted in the cylinder 3 and restson the angle or shoulder '8. The upper end of the shell 4 is acylindrical outer wick tube indicated at 9, which has an outstandingflange 10 at the top. The member 4 is held in place by rivets 11engaging inclined surfaces 12 on the flange 7 when the member 4 is setin place and turned slightly.

A central draft tube 13 is disposed within the shell 4 and is spacedtherefrom, being supported on a cross air pipe or tube 14 which extendshorizontally through the base 1 and the draft tube 13, and which has ahole 15 opening into the draft tube, so that air entering through thetube 14 may pass up and out through the tube 13 to the top of the wick.

A globe holder 16 is riveted to a cylindrical flange 17 depending from aring plate 18, and the flange 17 is also riveted to a band 19 which fitsupon or around cylinder 3, where it is held by the rivets 11 whichengage in bayonet slots 20 in the band 19, the rivets 11 being set inthe cylinder 3.

The upper tube 9 of the member 4 projects upwardly through the centralopening 21 in the ring plate 18, and this plate has holes 22 therein,and the flange 17 and band 19 have registering air holes Air enteringthrough these holes passes up inside and outside of the mantle 24through the openings 21 and 22. This mantle 24 is supported by a wire 26and a ring 25 which latter rests on the plate 18 where it is held bylugs 27.

A wick-raising tube 28 slides up and down on the central draft tube 13.This tube 28 has slots 29 in opposite sides thereof, to pass over thecross tube 14, and it is adjusted by a gear 31 engaging a rack 30 on thetube. The gear 31 is mounted on a shaft 32 supported by brackets 33projecting from the tube 14, and operated by a hand wheel 24.

The wick 35 fits over the tube 28 and has its lower end split asindicated at 36 and 37 to pass over the tube 14, and also split as at 38to pass over the gear 31 and rack 30. A cap 39 fits in the top of thecentral air tube 13 and is perforated as indicated at 40.

It will be seen that the flow of air is through the tubes 14 and 13 tothe interior of the mantle. Additional air is supplied through theopenings 21, 22, and 23, to support the combustion of the oil at the topof the wick and to cause incandescence of the mantle. The upper part ofthe burner and the mantle supported thereby can be lifted off by turningthe same to disengage the rivets 11 from the bayonet slots 20 in theband 19. This also permits the shell 4 and the tube 13 to be slipped outif desired.
